Title: Adjustable holder particularly useful for mounting magnetic heads
IPC: G11B5/50
Filed: 1976-05-08
Abstract: 1516045 Magnetic head supports BURROUGHS CORP 8 May 1976 19014/76 Heading E2A [Also in Division G5] An adjustable magnetic head holder permitting lateral head centering and azimuth adjustment relative to a record track RC has a support 2 for the head 6, and means 10 attaching the support 2 to a mounting 4 and allowing relative displacement therebetween, each of members 2, 4 including three coupling elements 30a, 30b, 30c and 40a, 40b, 40c respectively, having axes located to define the corner of an isosceles, and preferably equilateral triangle, all the axes being parallel and perpendicular to a plane containing the two triangles, the coupling elements 30 engaging with respective coupling elements 40 and one set of such elements being fixed relative to their member 2 or 4 and the other set being rotatable about their respective axes, each rotatable coupling element having means constraining the displacement relative thereto of the corresponding fixed element to a rectilinear path, azimuth adjustment being effected by rotating a first said rotatable element and centering adjustment being effected by rotating the other two rotatable elements through equal amounts in opposite directions to one another. Head 6 is resiliently held intermediate legs 16 of support 2 by closed-loop springs 22, and support 2 is attached to a carriage 4 by a fastener 10 around which support 2 is rotatable and which has a shank received in a vertically elongated opening 14 in carriage 4, the carriage 4 being mounted on pins in slots 8 therethrough. Fixed pins 40a to 40c on carriage 4 are received in grooves (38), Fig. 3a (not shown), diametral to the axes of rotatable coupling elements 30a, 30b, 30c which are equispaced from the axis of fastener 10 and have screwdriver slots (36a) to facilitate rotation. Starting from a position Fig. 5 (not shown), in which the groove (38a) in element 30a is vertical and the tangents (Tl), (T2) at pins 40b, 40c to the pitch circle (PC2) through pins 40a, 40b, 40c intersect at the centre point (HC) of the head gap, centering or height adjustment of head 6 is effected without affecting the azimuth setting by rotating elements 30b, 30c through equal and opposite angles. Azimuth or skew adjustment of the head is then effected by rotating element 30a. Unless the azimuth adjustment starts from a position in which said tangents (Tl), (T2) intersect at the gap centre point (HC), such azimuth adjustment also causes a height adjustment but this is usually small and can be corrected, if necessary, by rotating element 30a. Support 2 and head 6 can be removed and replaced on carriage 4 without the need for subsequent height and azimuth adjustment.

Patent GB-357581-A (GB)
Title: A process for the manufacture and production of mono-ethanolamine dinitrate or its homologues
Filed: 1930-06-23
Abstract: Monoethanolamine dinitrate, <FORM:0357581/IV/1> , and its homologues are manufactured by acting while cooling on monoethanolamine or a homologue thereof with excess of concentrated nitric acid and precipitating the dinitrate by pouring the solution into a cooled low molecular aliphatic alcohol or ether or a mixture thereof. Alternatively the base is first neutralized with the calculated amount of dilute nitric acid to produce the nitric acid salt, which is introduced into highly concentrated nitric acid.  The excess nitric acid may be recovered by extraction with water when using an ether for the precipitation, or, when an alcohol is employed, by neutralizing, e.g. with aqueous soda solution, and distilling off the alcohol, or preferably in either case by vacuum distillation of the nitration charge before precipitation.  In examples: (1) monoethanolamine mononitrate is treated at 0-10 DEG  C. with concentrated nitric acid and the solution poured with stirring into 95 per cent ethyl alcohol at 0 DEG  to -10 DEG  C.; (2) the nitration charge of (1) is poured into pure ethyl ether; (3) the nitration charge is distilled at 35-40 DEG  C. under a pressure of 11-12 mm. mercury gauge and the residue poured into 95 per cent ethyl alcohol at -10 DEG  to -15 DEG  C.; (4) as in (3) but using a mixture of ethyl alcohol and ethyl ether for the precipitation; (5) butanolamine is neutralized with dilute nitric acid, the mononitrate is added to concentrated nitric acid and the resulting solution added to a cooled mixture of ethyl ether and ethyl alcohol.  Other, though less suitable, liquids specified for the precipitation are methyl, propyl and butyl alcohols. Specification 350,293 is referred to.

Title: Improvements in or relating to insecticidal compositions
IPC: C07C17/02
Filed: 1954-06-30
Abstract: An insecticidal composition having a high order of toxicity for insects and a relatively low toxicity to warmblooded animals comprises the product formed by chlorinating a mixture of from about 37.5 per cent to about 70 per cent by weight of camphene, bornyl chloride, isobornyl chloride or a combination thereof and from about 30 per cent to about 62.5 per cent by weight of a body comprising a pinene e.g. alpha-pinene, beta-pinene, turpentine or mixtures thereof, to a chlorine content of about 50 per cent to about 70 per cent by weight of the chlorinated product.  The composition may be stabilized by adding from about 0.5 to about 5 per cent by weight of alpha-pinene, beta-pinene, camphene or turpentine to the chlorinated hydrocarbon blend.  The composition is preferably used in dilute form the diluent being, for example, an inert solvent as for example diesel oil, kerosene, xylene, vegetable oils or alcohol.  The composition may also be used as a water emulsion using emulsifying agents such as water-soluble soaps, alkaline salts of alginic acids, sulphonated fatty acids and alcohols, sulphated fatty acids, quaternary amines. Compatible knock-down agents such as pyrethrins, rotenone, allethrin, piperony butoxide may be incorporated.
